Abstract: A coolant control system of a vehicle includes a coolant pump that pumps coolant to a heat exchanger. A diesel exhaust fluid (DEF) injector injects a DEF into an exhaust system and receives coolant output from the heat exchanger. A fuel heat exchanger transfers heat between coolant and fuel flowing through the fuel heat exchanger. An engine control module is configured to determine a first requested speed for DEF injector cooling, determine a second requested speed for fuel cooling, and based on at least one of the first and second requested speeds, selectively increase at least one of: opening of a valve that controls a flow rate of fuel flowing from the fuel rail to the fuel tank, a flow rate of fuel from fuel injectors of an engine to the fuel tank, and a target speed of the coolant pump.

Abstract: Examples of techniques for controlling coolant flow in a vehicle cooling system for an internal combustion engine using a secondary coolant pump are provided. In one example implementation, a computer-implemented method includes receiving, by a processing device, engine operation data about the internal combustion engine. The method further includes detecting, by the processing device, a shutdown of the internal combustion engine. The method further includes calculating, by the processing device, an engine flow based at least in part on the block flow request and the head flow request. The method further includes, subsequent to detecting the shutdown of the internal combustion engine determining, by the processing device, an after-run condition based at least in part on the engine operation data. The method further includes activating, by the processing device, a secondary coolant pump based at least in part on determining the after-run condition.

Abstract: A coolant circulation system includes a coolant circuit including a water jacket, a motor-driven pump, an outlet liquid temperature sensor, and a controller. The controller executes variation determination control for driving the motor-driven pump to determine whether a variation in the temperature of the coolant in a diesel engine is equal to or less than a predetermined value based on an outlet temperature detected by the outlet liquid temperature sensor. The controller executes circulation stop control on condition that it is determined that the variation in the temperature of the coolant is equal to or less than the predetermined value. The controller changes the period during which the circulation stop control is executed in accordance with the outlet liquid temperature detected at the start of the circulation stop control.

Abstract: In an aspect, an electromechanical apparatus is provided, comprising an electromagnet, a magnetically permeable rotor, a drive, a current source, a current sensor and processing logic. The electromagnet includes a magnetically permeable housing and a wire coil disposed therein. The rotor spins and is disposed in the path of a magnetic circuit generated by the electromagnet. The drive rotates the rotor relative to the electromagnet housing. The rotor and electromagnet housing vary the reluctance therebetween as the rotor rotates. The current source applies a current to the electromagnet coil, wherein, during rotation of the rotor, fluctuations in the current result in the electromagnet coil due to the aforementioned varying reluctance are superimposed on the applied current. The current sensor senses fluctuations in current in the electromagnet coil. The processing logic reads the sensed current and determines the frequency of the fluctuations, which are correlated to rotor speed.
